So I just got done taking the head off and getting all the copper seal off the gasket, block and head. I was wondering if I should take some layers out of the gasket so I don't lose to much compression. I got the head and block decked plus the back part of the timing cover didn't get a amount of how much was taken off. Any one have this problem before? I don't have a caliper gauge to read what the thickness would be if I started taking layers out.
